- phoA4(Am)-- is Garen's phoAS26 . It is suppressed by leuX151, glnV33(=supE33) and serU132(=supD32).
- spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
- rrnB-2-- : loss of spacer loop sequence
- creC510-- The constitutive phenotype is due to an R77P amino acid substitution
- creC510 was formerly called phoM510
- = kanamycin resistant
- Am = amber(UAG) mutation
- Const = constitutive
- T2R = T2 Resistant
